What is the third term of the sequence defined by the recursive rule f(1)=3 f(n)=f(n-1)+4
Need f(2):
f(2)=f(2-1)+4
f(2)=f(1)+4
f(2)=(3)+4=7
FIND f(3):
f(3)=f(3-1)+4
f(3)=f(2)+4
f(3)=(7)+4
f(3)=11
2x-y=-5
-x-y=10
3x=-15
x=-5
-10-y=-5
-y=-5+10
-y=5
y=-5
HOPE I HELPED!!!
17,190 / 5,730 = 3. This means we must divide 70mg in half 3 times
70 / 2 = 35
35 / 2 = 17.5
17.5 / 2 = 8.75
There will be 8.75 mg left after 17,190 years.
To find the percent you take 18 and divide it by 48, so you get 9/24 or 3/8, by using calculator you get .375 which is 37.5% then you multiply by 100 to convert a decimal to a percentage.
